Does a blood test test for anemia?
A simple and common blood test used to test for anemia is CBC or the complete blood count. Technically you do not even need a CBC to just test for anemia. A simple Hemoglobin level can detect anemia. But a CBC will give your doctor some more information about the anemia if detected in your blood test. A CBC not only gives you your Hemoglobin level but it also gives you the counts of different types of cells in your blood. It will also give your doctor some more clues about possible causes of the anemia. Simply stated, anemia means a low hemoglobin level in the blood. A hemoglobin level below 8 is critical anemia and normally requires blood transfusion.
